More details about AMD's Trinity APU were leaked by Expreview. According to the slides the new Piledriver cores will have a higher IPC instructions per clock while leaking less power. Trinity is anticipated...

I'd say a GPU core that's 50% faster than HD4000 would be a nice selling point. Llano is already 30% faster atm. In times of GPGPU that should be noticeable outside of games. But with APU's the one that doesn't stutter wins, which is mostly driver related, I guess.
